I This invention relates to improvements in eyeleting machines formattress borders.

In certain types of mattresses the border portions are formed with rowsof spaced me- .gtallic eyelets which serve to join the border layers.Heretofore difficulty has been e11- countered in the insertion of theseeyelets, especially Where the borders are of such width that the eyeletsmust be disposed in spaced transverse rows. 1

It is one of the objects of'the present invention to provide a machinewhich will feed the several materials required for a mattress border sothat the same will be disposed in .their proper relation and then atintervals .join said layers by transverse rows of a plu- .30. A furtherobject of the invention is to provide an eyeleting machine for mattressbor ders which is of very simple construction, is rapid, eflicient andautomatic in operation, is strong and durable, and is well adapted forthe" purposes described.

With the above and other objects in view the invention consists of theimproved eyeleting machine and its parts and combinations as set forthin the claims, and all equivalents thereof.

. Fig. 9 is an enlarged detail sectional View Referring now moreparticularly to the drawings it will appear that the numeral 12indicates a supporting table having a flat base portion 13, at one endof which the improved eyeleting machine, indicated generally by thenumeral 14, is mounted. Said machine is formed with a pair ofupstanding, spaced frame members 15 formed at their upper ends withbearings 16 in which is journaled a transverse crank shaft 17, one endportion of said shaft having mounted thereon, by means later to bedescribed, a large drivewheel 18. Pivotally secured to and dependingfrom the crank portion 19 of said crank shaft-is a crank arm 20 which ispivotally mounted at its lower end portion on a rod 21 which is carriedfast by a pair of spaced lugs 22 projecting outwardly from a verticallymovable angled plate 23. The large drive wheel 18 is driven by a belt 24wh1ch-extends to a pulley mounted fast on a shaft 26 with a largerpulley 27, the larger pulley being connected through a belt 28 with anelectric motor 29. Said motor and the pulleys 25 and 27 are mountedbelow the base portion 13 of the table, as shown in Fig. 1. a

Mounted fast onthe end portion of the crank shaft 17 is a pulley member30 having an outwardly extending sleeve portion 31 on which the largedrive wheel 18 is mounted, there being a clutch engagement. of anycommon form between said drive wheel and the sleeve, controlled by aplunger 32 yieldably mounted within a groove 33 of said pulley member.An operating lever 34 is pivotally mounted on the frame portion 15 andconnected thereto is a vertical rod 35 normally maintained in a raisedposition by a spring 36 coiled thereabout. If the lever 34 be helddownwardly, the rod 35 will be disengaged at its upper end portion fromthe groove 33 and plunger 32 and there will be a clutching engagementbetween the members 30 and 18 whereby they will turn together when thepower is on. If the lever 34 be released, the upper end portion of therod 35 will engage the plunger 32 and the clutch engagement between thedrive wheel and member 30 will be released whereby the drive wheel willidle on the sleeve portion 31 and the crank shaft 17 will not be turned.

A slotted crank member 37 is connected fast to the outer end portion ofthe sleeve portion 31 and a wrist pin 38 is adjustably connected to thecrank member, whereby the stroke of a connecting rod 39, connected atits upper end portion to the wrist pin, may be varied. The lower endportion of the connecting rod is pivotally connected to the outer endportion of an arm 40 mounted fast on the end portion of a shaft 41 whichis journaled in the bearing portion of a supporting arm 42, and theother end portion of said shaft has pinned thereto an arm 43 at rightangles to the arm 40. A dog member 44,movable against a spring 45, iscarried by the outer end portion of the arm 43. A cam 46 is mountedloosely on the end portion of the shaft 41 and its shoulders 47,separated by ninety degree angles, are adapted to be engaged by the dog44, whereby said cam member is inter mittently moved a quarter of arevolution. Also mounted loosely on the shaft 41 and secured to the cam46, so as to make quarter revolutions therewith, is a gear 48 which isin mesh with a. gear 49 mounted fast on the end portion of an upperroller shaft 50. Said shaft 50 is journaled in adjustable bearings 51and has mounted fast thereon a feed roller 52. A lower guide roller 53cooperates with the feed roller, and said guide roller is mounted on ashaft 54 below the shaft 50 and parallel thereto.

Extending upwardly and forwardly from the frame portion of the machineis an angular supporting arm 55 on the enlarged outer 1 end portion ofwhich are mounted three eyelet casings or boxes 56, 57 and 58, eachbeing provided with a cover 59 to permit the loading of eyelets. Thesupporting-arm, below each box, is provided with a bearing in which isjournaled a brush shaft 60, each brush shaft extending into its box andhaving mounted on its inner end portion a brush 61 and havmg mounted onits outer end portion a pulley 62. A belt 63 is extended around all ofsaid pulleys to drive the brushes, and said belt also extends oversheaves 64 and around the pulley member 30 on the crank shaft 17.

Eyelet raceways 65, 66 and 67 mounted on a surface of the supporting arm55, extend from the boxes 56, 57 and 58, respectively, to the lowercurved end portion of said arm. When the brushes 61 within the boxes arerevolved eyelets 68 within the boxes are tossed around and areultimately worked, in proper positions, through openings 69 in thesldesof the boxes, each box opening registering with the racewayadjacent its box. The raceways 65, 66 and 67 are constructed as shown inFigs. 7 and 10 and the eyelets are held therein as shown in Fig. 10 anddescend by gravit to the lower end portions of the raceways. he lowerend portion of each raceway is provided with a pair of movable, springconnected fingers 70 whichengage and releasably hold the adjacenteyelets under their headed end portions for the eyeleting operation.

The vertically movable plate member has secured transversely to itslower end portion a block 71 having a dove-tailed recess 72 whichreceives the dove-tailed p0rtions'73 of three eyeleting punch members74. Y The unch members 74 are provided with clampmg bolts 75 engagingthe bar 71 and by the dove-tailed arrangement said members 74 may beadjusted laterally, when required.

A unch member is shown in detail in Figs. 5 and 6 and will be seen tocomprise a cylindrical portion 74 having a bore 76 extending upwardlyfrom its lower end portion. A reduced stem portion 77 is secured withinthe lower portion of the bore by the set screw 75 and depends from theportion 74', said stem portion having a reduced bore 78. An elongatedplunger 7 9 is movably mounted within the bore 78 and its head 80extends within the bore 76 and mounted on said head, within the latterbore, is a coiled spring 81.

Mounted fast on a frame portion 82, below the punch members 74 andspaced there from, are three die members 83. Each die member has arecess 84 in which is positioned an upwardly projecting cylinder 85, theposition of the cylinder being adjustable by means of an adjusting bolt86. The frame portion 82 carries a movably mounted material supportingplate 87 which is yieldingly movable against the tension of a spring 88,aving a t'nsioning adjustment 89. Said plate 87 supports 9. fed mattressborder 90 between the punch members and the die members and is formedwith a plurality of recesses or cut-out portions 91 to permit passage ofthe punching plungers 79.

In the construction of mattress borders with the improved eyeletingmachine, a pile] of ticking 92 is arranged rearwardly of the supportingtable 12, as shown, and said ticking 1s extended over rollers 93 mountedat the upper end portions of elongated posts 94 projecting u wardly fromthe table portion 13. The tic ing 92 is then drawn downwardly and entersa guide apron 95 extended rearwardly from the-machine frame 15, and isdisposed between the punch members and the die members and between therollers 52 v and 53, which causes it to be fed forwardly.

A pile'of ticking 96 for the under layer of the mattress border ispositioned under the table 12, as shown in Fig. 1, and said materialisextended upwardly through a slot 97 in the table base 13 to a guideapron 98, and then between the punch members and dies, over thesupporting plate 87, to the feed rollers 52 and 53.

A large rollof cotton felt 99 is mounted on a. roller 100 carried by anintermediate portion of the forward post 94 and said felt rovides theintermediate layer or stufiing or the mattress border. Said felt extendsto an apron 101 and then between the rollers 52 and 53, interposedbetween the upper and lower ticking layers 92 and 96; When the mattressborder material is arranged as described and the machine is set inoperation, it being necessary for the operator to hold the lever 34down, the feed rollers will be intermittently turned through theconnecting rod 39, arms 40 and 43, cam 46, and gears 48 and 49 to feedthe material forward a desired distance; Then, while the rollers arestationary, the crank 19, through the arm 20, will'lower the plate 23carrying the punch members 74. As the puch members move downwardly theplungers 79 thereof will pass through the eyelets held ready forinsertion at the ends of the tracks 65, 66 and 67, by the fingers 70,and the plungers will also pierce the mattress border material,ultimately engaging projecting portions 102 of the die members. Afurther downward movement of the punch members will cause the punchmembers to engage and force the eyelets into the material, as in Fig. 5,the lungers being movable in the cylinder bores 2 against the expansiveforce of the springs 81. Also, the lower end portions of the eyeletswill be forced against the die members and be flanged or headed thereby,as in Fig. 6. After this operation the plate carrying the punch membersis raised, releasing the punch plungers from the inserted eyelets, saideyelets being in a spaced transverse row and securing togetherthe'border material layers and giving it a tufted appearance. As

shown in Fig.- 2, the downward movement of the plate 23 is against thetension of a coiled spring 103, and a smaller coiled spring 104, betweenthe upper end portion of the plate 23 and a lug 105, cushions the upwardmovement of said plate. It should also be observed that the-angularraceway supporting arm 55 is provided with intermediate lugs 106 throughwhich a rod 107 extends to pivotally attach said arm tothe frameportions 14 and 15. During punching operations said arm 55 pivotsslightly in a clockwise direction, in Fig. 2, against the force of aspring 108 mounted on a horizontal rod 109, and when the punch membersare raised, said spring returns the arm to normal position.

After the punch plate is raised to normal position, through themechanism described, the material is fed forwardly a predetermineddistance and then another transverse row of eyelets is inserted, and soon.

From the foregoing description it will be seen that the improved machineprovides for having fed thereinto from three different sources, threelayers of mattress border material. The machine feeds the material,inserts transverse rows of eyelets to secure the material layerstogether, and then spaces the material for the-next eyeleting operation.There is delivered from the machine a length of substantially completedmattress border, which, because of the eyelets, is especially 'suitedfor ventilated mattresses and is attractive. Also, the machine is simpleand efficient in operation and is well adapted for the purposesdescribed.
